Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance. Selection between substitutes depends on circuit voltage requirements and tolerance specifications:

For 630V applications requiring ±20% tolerance: The original 1812CC472MAT1A or 1812GC472MAT1A (2kV rated) are suitable.

For applications requiring improved tolerance (±10%): 1812AC472KAT1A (1kV), 1812GC472KAT1A (2kV), KGM43FR73D472KV (2kV), or C4532X7R3A472K160KA (1kV) are available.

For higher voltage margin (2kV rating): 1812GC472KAT1A, 1812GC472MAT1A, or KGM43FR73D472KV provide enhanced voltage headroom.

For cross-manufacturer compatibility: C4532X7R3A472K160KA (TDK Corporation) offers equivalent electrical performance with identical package footprint.

Physical board space constraints must account for thickness variations: original and 1kV-rated parts measure 1.80mm maximum thickness, while 2kV-rated parts measure 2.20mm to 2.21mm maximum thickness.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a direct substitute? A: Yes. All substitute parts rated at 1000V or 2000V are electrically compatible with the 630V application. Higher voltage ratings provide additional safety margin and do not degrade circuit performance.

Q: What is the difference between ±10% and ±20% tolerance? A: Tolerance specifies the allowable deviation from the nominal 4700 pF capacitance value. ±10% tolerance (4230 pF to 5170 pF) provides tighter capacitance control than ±20% tolerance (3760 pF to 5640 pF). Selection depends on circuit sensitivity to capacitance variation.

Q: Are there physical size differences between substitute parts? A: All parts use the 1812 (4532 Metric) package with identical length (0.181" / 4.60mm) and width (0.126" / 3.20mm). Thickness varies: 630V and 1kV-rated parts measure 1.80mm maximum, while 2kV-rated parts measure 2.20mm to 2.21mm maximum. Verify PCB clearance for higher-voltage substitutes.

Q: Is the TDK C4532X7R3A472K160KA compatible with KYOCERA AVX designs? A: Yes. The TDK part maintains identical capacitance, temperature coefficient, package footprint, and compliance certifications. Slight dimensional variation (0.177" L vs. 0.181" L) remains within 1812 package specification tolerance.

Q: Do all substitutes have the same moisture sensitivity level? A: Yes. All listed parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Which substitute offers the best overall performance upgrade? A: Selection depends on application requirements. For voltage margin: 2kV-rated parts (1812GC472KAT1A, 1812GC472MAT1A, KGM43FR73D472KV). For tolerance precision: ±10% parts (1812AC472KAT1A, 1812GC472KAT1A, KGM43FR73D472KV, C4532X7R3A472K160KA).
